The aim of present study was to find out the influence of oxygen and nitrogen containing ethanolamine oligomers on the tribological behavior. X-ray photoelectron spectroscopy (XPS) was used to obtain insight into the molecular mechanisms leading to the macroscopic lubricity. Monomolecular lubricant films were deposited onto ultra thin copper films sputtered onto silicon wafers. Surfaces covered...

Fuel contamination of engine lubricating oil has been previously determined to arise from two independent phenomena: the effect on flash point, and changing lubrication conditions tribological pairs. This paper combines these effects holistically analyzes consequences fuel in a trunk piston risk crankcase explosion. The author hypothesized that diesel as an contaminant increases explosion due i...

Vegetable-oil-based biolubricants are an excellent alternative to conventional lubricants. Instead of focusing on novel feedstocks, these should be further elucidated based their fatty acid composition, which influences tribological properties. Therefore, the study utilises gene expression programming (GEP) derive a boundary lubricity model for vegetable-oil-derived trimethylolpropane (TMP) est...

Purpose To determine whether the adaption of neophytes to rigid gas permeable lenses (GPs) could be accelerated by changing their diameter or surface lubricity. Methods This was a 2 part prospective double-masked randomised wear study. An GP lens (Roflufocon D material, 9.6 mm diameter) with and without Hydrapeg plasma coating worn 119 (21.1 ± 3.5 years; 77% female) on separate occasions. A fur...
